Description:
Observations in the recent decade have revealed many thermospheric density corrugations/perturbations under non-storm conditions (Kp〈2). They are generally not captured by empirical models like MSIS, but are operationally important for long-term orbital evolution of Low-Earth-Orbiting satellites and theoretically for coupling processes in the atmosphere-ionosphere system. We review these density corrugations by classifying them into three types which are driven respectively by the lower atmosphere, ionosphere, solar wind/magnetosphere. Model capabilities in capturing these features are discussed. A summary table of these corrugations is included to provide a quick guide on their amplitude range, occurring latitude, local time and season.
